Semenya tweeted this on the day the new rules were announcedWhat do the new rules say[/IMG]It pointed to their latest research which showed there is a performance advantage for females with higher testosterone over the track distances.How did we reach this point?Media playback is not supported on this deviceCaster Semenya: The full interviewSemenya, then 18, was asked to take a gender test shortly before she won the 800m at the 2009 World Championships in Berlin.Athletics South Africa president Leonard Chuene later admitted that he had lied to Semenya about the purpose of the test, having told her it was a random doping test.The results were not released - although there were media reports[/i] that her test had revealed male and female characteristics - and Semenya was cleared to return in July 2010.Indian sprinter Chand became the first athlete to challenge the IAAF's policy around so-called gender tests and naturally high testosterone levels in female athletes in 2015.As an 18-year-old, Chand was given a hormone test, and found out from reading the press that her natural levels of the hormone testosterone were normally only found in men. She successfully challenged her subsequent ban, which led to the Court of Arbitration for Sport (Cas) suspending the IAAF's "hyperandrogenism" rules for two years. Cas expressed concerns over the lack of evidence proving the precise degree of competitive advantage that a hyperandrogenic athlete would possess, and gave the IAAF two years to prove its case.Research commissioned by the IAAF in July 2017 found that female athletes with high testosterone levels had a "competitive advantage".However, critics of the governing body have said its stance is discriminatory, and highlighted the possible psychological effects on those who have to take the tests.What is the history of gender testing?

German officials examined Helen Stephens (left) before the Games and declared her female; an autopsy of Stella Walsh 40 years later revealed she had ambiguous genitalia.1936: Polish runner Stella Walsh and America's Helen Stephens are accused of being male imposters during the Berlin Olympics.1938: German high jumper Dora Ratjen is identified as male, and Germany return the gold medal won at the European Championship. Der Spiegel wrote in 2009 that Ratjen was born with ambiguous genitalia[/i] and was raised as a girl at the suggestion of a midwife.1968: International Olympic Committee begin comprehensive "gender testing".1972-1984: 13 women "fail" gender tests.1985: Spanish hurdler Maria Jose Martinez-Patino is told her chromosome test is abnormal. Martinez-Patino refuses to quit or feign injury, and further investigation reveals that a genetic condition meant she was insensitive to testosterone that was in her blood.2009: Caster Semenya is asked to take a gender test and the results are reported in the media.2014: Dutee Chand is banned from competing after results of a gender test.2015: Chand has her ban overturned and the IAAF rules requiring female athletes to take testosterone-suppressing medication are suspended for two years.
